How long does it take to charge a car battery at 6 amps?

I need to charge my car battery with a 6-amp charger. How long will this take? My car is dead but I’m supposed to leave for a work trip tomorrow.

The amount of time to charge your car battery at six amps depends on the size of your battery. If your battery is fully drained, charging it at six amps will take:
  • Eight to 10 hours to charge a small car battery of about 200 to 315 cold cranking amps (CCA) or reserve capacity (RC) 40 to 60.
  • 10 to 12 hours to charge a mid-sized battery of 315 to 550 CCA or RC 60 to 85.
  • 12 to 24 hours to charge a large car battery of 550 to 1,000 CCA or RC 85 to 190.

jump your car
instead, drive your car for at least 30 minutes to charge up your battery.
